Application filed July '15, 1912. Se'r'ial No. 709,311.

Be it known that I RICHARD C. Rose, a

citizen of the United States, residing at Osceola, in. the county of Mississippi and State of Arkansas,have invented a new and useful Internal- Combustion Engine, of which the following is a specification.

The present invention relates to improvei ments in internal combustion engines, the! primary object of the invention being the: provision of a sliding sleeve valve engine In which two oppositely disposed pistons are mounted, each piston having its individual crank shaft and said crank shafts being operably connected to properly transmit the power generated by both pistons to one of said crank shafts, two sleeve valves being preferably employed and so constructed an arranged as to provide a centrally disposedcombustion chamber so that a single intake and exhaust disposed upon the same slde of the cylinder may be employed, the pistons when moving toward each other compressing the explosive charge therebetween and being propelled-away from each other simultaneously due to the explosion of the charge.

A further object of the present invention is the provision of a sliding sleeve internal combustion engine, in which one of the sleeves carries the spark plug, said spark plugbeing movable into and out of electrical connection so that the spark is energized when the pistons are at their highest point of compression to thus secure the maximum power from the explosion.

With the foregoing and other-objects in view which will appear as the description proceeds, the invention resides in the oombination and arrangement of parts and in the details of. construction hereinafter described and claimed, it being understood that changes in the precise embodiment of the invention herein disclosed can be made within the scope of what is claimed without departing from the spirit of the invention.

In the drawings Figure 1 .is a longitudinal sectional view on line 11 of Fig. 2.

designates the cylinder of the engine, which i is surrounded by the water jacket -2 provided with the depressed or recessed ortion 3 in one side thereof, the urpose 0 will presently appear. his cylinder is also provided with the intake .port 4 and the exhaust port 7, the intake port 4 having led thereto an intake conduit 5 led from the manifold 6, while the exhaust ort communicates with the exhaust con uit 8 led into an exhaust manifold 9-. It will thus be seen that both the intake and exhaust ports of the present invention are disposed near the center of the cylinder and that a single explosive chamber C is provided to actuate both of the power pistons 25 and 28 as will presently appear. Slidably mounted within and forming the lining for the cylinder 1, is the external concentric sleeve valve 10 provided with the intake port 11 and the exhaust port 12, said ports being positioned in such spaced relation, that when one port is in al-inement with its respective intake or exhaust port of the cylinder 1, the other will be out of registration, while mounted slidably within the outer concentric sleeve valve 10 is the inner concentric sleeve valve 14 provided with a single port 15, which is adapted at the proper time to register with either one of the ports 11 or 12 of the outer sleeve valve 10 to permit of the proper admission of the explosive charge into the chamber C or the exhaust of the burnt gases therefrom. The sleeve valve 10 upon the diametrically opposite side from the ports 11 and 12 is provided with the elongated slot 13, while mounted in the orifice 17 of the inner sleeve valve 14, is a spark plug 18, said spark plug being carried by the sleeve 14 and slidable within the slot 13 of the sleeve 10. By this means it will be seen that the spark plug 18 will be moved longitudinally of the cylinder 1 and that by reason of the terminal 19 thereof being disposed to be placed into and outof engagement with the contact plate 20 disposed in i which in the inner valve sleeve 14 and are disposed to move in consonance toward and awayfrom the center of the engine.

.In order to properly operate the outer concentric sleeve valve 10 in proper time with the reciprocation of the power pistons and 28, a gear 29 is keyed upon the crank shaft 23 and operates the gear 30, which in turn actuates the crank shaft 31, which is connected through the medium of the link 32 to the lugs 33 ofthe sleeve valve 10.

' r-In order that the sleeve valve 14 may be operated in time with the power pistons 25 and 28, and also the sleeve valve 10, a gear 34 is keyed upon the lower crank shaft 26 and actuates the gear 35 which through the crank shaft 36, and the links 37 and lugs 38 is operably connected to the valve sleeve 14.

A large gear, or in fact any other transmission means is connected to the crank shaft 23 and is in mesh at all times with a large gear 40 mounted upon the crank shaft 26, thus properly holding in timed relation the respective crank shafts-23 and26, so that the reciprocation of the power pistons 25 and 28 will impart the desired movement to the main crank shaft 26 and the balance or fly-wheel 41.

From the foregoing description taken in connection with the drawings it wlll be seen that the actuation of the respective pistons '25 and 28 through their respective crank shafts 23 and 26, will control in proper time the reciprocation of the two slidlng sleeve valves 10 and 14 so that the ports 11 and 12 of the sleeve valve 10 will be placed into and out of registration with the ports 5 and 7 of the cylinder 1, while the port 15 of the sleeve valve 14: will control the admission and exhaust of the explosive charge and burnt gases to and from the explosive chamber C of the engine. It will also be noted that, by this construction of sleeve valve, that a four cycle engine is provided and that the explosive charge is admitted after the cylinder has been properly scavenged and that the spark plug 18 will be energized at the proper time during the compression of the explosive charge between the respective power pistons 25 and 28 and when all of the ports of the cylinder and sleeve valves 10 and 14 are out of registration.

By the particular arrangement and position of the spark plug 18, the usual complicated timing devices are dispensed with I and by reason of the recess 3, the plug may be readily attached and removed.

What is claimed is;

1. An internal combustion engine, having a cylinder open at both ends and provided with an intake and an exhaust port uponone side centrally thereof, a pair of oppositely disposed power pistons mounted in the cylinder and coupled ,for simultaneous movement and to provide a central combustion chamber in the cylinder two concentric sleeve valves mounted forshding movement within the cylinder and about the pistons, the outer sleeve valve having tWo ports for registration with the respective intake and exhaust ports of the cylinder, while the inner cylinder has a single port-for registration with either one of the ports of the outer sleeve valve, means for operably con,- necting the outer sleeve valve to one power piston, and means for operably connecting the inner sleeve valve to the other power.
